Enable Driver Event Logging — Without the Mess
A short, friendly walkthrough of enabling extra driver event logging when you need a deeper look.
A short, friendly walkthrough of enabling extra driver event logging when you need a deeper look.
Drivers normally log only major events — startup, shutdown, fatal stops. When knowledge an intermittent issue, the default log is often too sparse to be useful. Enabling extra event logging captures the smaller decisions the driver makes along the way.
The result is much more data, but with the right filters in place, the relevant events are easy to find. The trade-off in disk space is small for the duration of an investigation.
Many drivers expose a registry value or configuration file that controls log verbosity. The maker's knowledge base usually documents the specific value to set. After changing it, restart the affected service or the system to pick up the new level.
Event Tracing for the operating system also offers per-driver logging without registry changes. The Performance Monitor tool can start and stop these traces with a friendly interface.
The Event Viewer offers filters by source, level, and time window. Apply them aggressively — looking at "all events" from a verbose driver is overwhelming. Filtering to a fifteen-minute window around the issue you are investigating focuses the view.
When you finish, return logging to the default level. Verbose logging is meant to be temporary, and leaving it on indefinitely can fill the disk on busy systems.
